Merge tag 'drm-next-2023-02-23' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "There are a bunch of changes all over in the usual places.

  Highlights:

   - habanalabs moves from misc to accel

   - first accel driver for Intel VPU (Versatile Processing Unit)
     inference engine

   - dropped all the ancient legacy DRI1 drivers. I think it's been at
     least 10 years since anyone has heard about these.

   - Intel DG2 updates and prelim Meteorlake enablement

     with inference accelerators)

25e0e5ae56 drm/i915/display: Do both crawl and squash when changing cdclk
For MTL, changing cdclk from between certain frequencies has
both squash and crawl. Use the current cdclk config and
the new(desired) cdclk config to construct a mid cdclk config.
Set the cdclk twice:
- Current cdclk -> mid cdclk
- mid cdclk -> desired cdclk

Driver should not take some Pcode mailbox communication
in the cdclk path for platforms that are Display version 14 and later.

v2: Add check in intel_modeset_calc_cdclk() to avoid cdclk
change via modeset for platforms that support squash_crawl sequences(Ville)

v3: Add checks for:
- scenario where only slow clock is used and
cdclk is actually 0 (bringing up display).
- PLLs are on before looking up the waveform.
- Squash and crawl capability checks.(Ville)

v4: Rebase
- Move checks to be more consistent (Ville)
- Add comments (Bala)
v5:
- Further small changes. Move checks around.
- Make if-else better looking (Ville)

v6: MTl should not follow PUnit mailbox communication as the rest of
gen11+ platforms.(Anusha)

9a0a4ec530 drm/i915/display: Add missing checks for cdclk crawling
cdclk_sanitize() function was written assuming vco was a signed integer.
vco gets assigned to -1 (essentially ~0) for the case where PLL
might be enabled and vco is not a frequency that will ever
get used. In such a scenario the right thing to do is disable the
PLL and re-enable it again with a valid frequency.
However the vco is declared as a unsigned variable.
With the above assumption, driver takes crawl path when not needed.
Add explicit check to not crawl in the case of an invalid PLL.

v2: Move the check from .h to .c (MattR)
- Move check to bxt_set_cdclk() instead of
intel_modeset_calc_cdclk() which is directly in
the path of the sanitize() function (Ville)

v3: remove unwanted parenthesis(Ville)

801543b259 drm/i915: stop including i915_irq.h from i915_trace.h
Turns out many of the files that need i915_reg.h get it implicitly via
{display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h
-> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h,
makes sense to drop it, but that requires adding quite a few new
includes all over the place.

Prefer including i915_reg.h where needed instead of adding another
implicit include, because eventually we'll want to split up i915_reg.h
and only include the specific registers at each place.

Also some places actually needed i915_irq.h too.

e30e6c7b82 drm/i915: Move MCHBAR registers to their own header
Registers that exist within the MCH BAR and are mirrored into the GPU's
MMIO space are a good candidate to separate out into their own header.

For reference, the mirror of the MCH BAR starts at the following
locations in the graphics MMIO space (the end of the MCHBAR range
differs slightly on each platform):

 * Pre-gen6:           0x10000
 * Gen6-Gen11 + RKL:  0x140000

v2:
 - Create separate patch to swtich a few register definitions to be
   relative to the MCHBAR mirror base.
 - Drop upper bound of MCHBAR mirror from commit message; there are too
   many different combinations between various platforms to list out,
   and the documentation is spotty for the older pre-gen6 platforms
   anyway.

This feature works also when display codec is in D3 state and the audio
link is off (BCLK off). To enable this functionality, display driver
must update the AUD_TS_CDCLK_M/N registers whenever CDCLK is changed.
Actual timestamps are generated only when the audio codec driver
specifically enables the KeepAlive (KAE) feature.

This patch adds new hooks to intel_set_cdclk() in order to inform
display audio driver when CDCLK change is started and when it is
complete.

4dd4375bc4 drm/i915: split out intel_pcode.[ch] to separate file
The snb+ pcode mailbox code is not sideband, so split it out to a
separate file. As can be seen from the #include changes, very few places
use both sideband and pcode.

Code movement only.

1eecf31e3c drm/i915: split out vlv sideband to a separate file
The VLV/CHV sideband code is pretty distinct from the rest of the
sideband code. Split it out to new vlv_sideband.[ch].

Pure code movement with relevant #include changes, and a tiny checkpatch
fix on top.

2a764b7c70 drm/i915/display: Fix the dsc check while selecting min_cdclk

Hence use dsc_split instead of slice_count while selecting the

fe01883fdc drm/i915: Get proper min cdclk if vDSC enabled
VDSC engine can process only 1 pixel per Cd clock. In case
VDSC is used and max slice count == 1, max supported pixel
clock should be 100% of CD clock. Then do min_cdclk and
pixel clock comparison to get proper min cdclk.

v2:
- Check for dsc enable and slice count ==1 then allow to
  double confirm min cdclk value.

46b0d7091c drm/i915: Make display workaround upper bounds exclusive
Workarounds are documented in the bspec with an exclusive upper bound
(i.e., a "fixed" stepping that no longer needs the workaround).  This
makes our driver's use of an inclusive upper bound for stepping ranges
confusing; the differing notation between code and bspec makes it very
easy for mistakes to creep in.

Let's switch the upper bound of our IS_{GT,DISP}_STEP macros over to use
an exclusive upper bound like the bspec does.  This also has the benefit
of helping make sure workarounds are properly handled for new minor
steppings that show up (e.g., an A1 between the A0 and B0 we already
knew about) --- if the new intermediate stepping pulls in hardware fixes
early, there will be an update to the workaround definition which lets
us know we need to change our code.  If the new stepping does not pull a
hardware fix earlier, then the new stepping will already be captured
properly by the "[begin, fix)" range in the code.

We'll probably need to be extra vigilant in code review of new
workarounds for the near future to make sure developers notice the new
semantics of workaround bounds.  But we just migrated a bunch of our
platforms from the IS_REVID bounds over to IS_{GT,DISP}_STEP, so people
are already adjusting to the new macros and now is a good time to make
this change too.
